I like 1 and 2 the best, very shallow Dof. Pose is nice and natural. Maybe its just me, but the eyes seem barlely out of focus. On 2 I love everything about it except the letters on the bench kinda throw it off for me. Beautiful wife btw.
Your wife and model is stunning.... and the photos are really excellent too.
The only thing that doesn't gel in my head is the new look to this. Ideally it would have been set back in the '30's, and the photo would have had a completely different look about them. I think it's because we have become conditioned through media to expect a certain look from a particular era.
I hope you don't mind, but I experimented with one of your photos, just to give you an idea what I'm talking about... Please let me know if you want me to remove it....no probs at all.
Left: direct positive, mid: Antique, right: sepia.
Personally, I really like the Direct pos on the left.
Agree w/ previous comments wrt to focus, exposure et al. Something I think might make these images really stand out is to do selective colourations; that is a B&W subject and colour background or vice versa; sort of grab the dichotomy already there, and slap you in the face with it.
